As a leading High-Quality Sandwich Panel Roofing Sheets Manufacturer & Exporter, Shaanxi YuanShengHeTong Refrigeration Equipment Co., Ltd. has stood at the forefront of thermal envelope technology since 1996. In the modern era of industrial construction, the demand for roofing materials has shifted from simple protection to sophisticated "thermal management systems."
Sandwich panels, particularly those utilizing Polyisocyanurate (PIR) and Polyurethane (PU) cores, represent the pinnacle of this evolution. These panels are not merely sheets; they are engineered composites designed to minimize thermal bridging, provide structural rigidity, and meet stringent fire safety standards (B1/B2 grades). Our 20+ years of expertise allow us to integrate one-stop project solutions that encompass design, manufacturing, and international logistics.
Transitioning from traditional EPS to PIR cores significantly improves fire resistance. Our PIR panels offer a carbonization layer that prevents flame spread, crucial for high-value logistics hubs.
By optimizing foam density to 40-42 kg/m³, we achieve thermal conductivity as low as 0.019 W/m·K, reducing energy consumption for cold storage facilities by up to 35%.
As of 2023, our technical roadmap focuses on pentane-blown foaming processes, eliminating ODS (Ozone Depleting Substances) and reducing GWP (Global Warming Potential) to near zero.
We provide systemic solutions for diverse sectors, recognizing that a "High-Quality Sandwich Panel" is only effective when integrated into a well-engineered environment. Our professional fields include:
Customized PU/PIR panels for fruit, vegetable, and meat processing plants where hygiene (HACCP) and temperature stability are paramount.
Ultra-stable temperature environments for medical and vaccine storage, utilizing our advanced air coolers and cam-lock sandwich panels for airtight integrity.
Large-scale roofing and wall solutions for 3PL providers, focusing on structural durability and rapid installation to minimize TCO (Total Cost of Ownership).
Our Shaanxi-based facility is a testament to China's manufacturing upgrade. By integrating "Smart Manufacture" with "High Quality Products," we ensure our global clients receive top-tier materials without the lead-time volatility seen elsewhere.
For global enterprises, procurement is about more than just price—it's about compliance. We ensure that our Sandwich Panel Roofing Sheets meet international building codes and environmental standards.
Our products carry CE Certification and comply with ISO quality management systems, ensuring seamless customs clearance and building permit approvals.
With expertise in international trade, we provide optimized packing solutions for sandwich panels to prevent edge damage during transit, utilizing sea-worthy protection.
We don't just ship panels; we provide detailed CAD installation guides and remote technical consulting to ensure local contractors achieve perfect thermal sealing.
While both offer excellent insulation, PIR (Polyisocyanurate) has superior fire resistance and a higher thermal stability compared to standard PU (Polyurethane). PIR is often preferred for large-scale industrial projects where safety regulations are stricter.
Our panels are designed with high-quality pre-painted galvanized steel (PPGI) or stainless steel skins. With proper installation and maintenance, the structural and thermal lifespan exceeds 25 years in most industrial environments.
Yes, we offer thicknesses ranging from 50mm to 200mm. A 100mm PIR panel typically provides an R-value of approximately 5.0 (m²·K/W), which is ideal for most cold storage applications.
Absolutely. We are an integrated enterprise. Beyond panels, we manufacture air coolers, condensers, and compressor units to provide a holistic cold storage solution.
